ANAHEIM, Calif. — There's no quit in the UCLA Bruins. Good thing, since they keep finding trouble and inventing ways to escape.

Darren Collison scored the go-ahead basket on a one-handed layin with 9 1/2 seconds remaining, Josh Shipp blocked Donald Sloan's final drive and the West Region's No. 1 seed held on for a 53-49 victory over Texas A&M in the second round of the NCAA tournament last night.

"Once the time clock goes zero, zero, we'll stop playing," Collison said. "We've been through that all season. We knew what we had to do; we knew who was going to win, and all the coaches said we just had to do the right things to win the game."

The Bruins (33-3) won their 12th in a row and will face the winner of Western Kentucky-San Diego next week in Phoenix. Their 33rd win is a record at the tradition-laden school that has 11 national championship banners, and their 96th NCAA tourney victory trails only Kentucky's 100.

"That was reminiscent of a lot of games we seem to be in lately, where we're having to make dramatic comebacks in the last few minutes," UCLA coach Ben Howland said. "But the one thing that I love about our team is that they know in their heart they're always going to win the game. They're going to find a way."

Urged on by a pro-UCLA crowd that made it seem like a home game, the Bruins rallied from a 10-point deficit in the second half.

Freshman Kevin Love had 19 points and 11 rebounds — his 21st double-double — and UCLA overcame the combined 3 for 14 shooting of Shipp and Russell Westbrook. Love had seven of UCLA's 11 blocked shots.

"I was just very into it," said Love, who squeezed the ball and screamed toward the crowd during a late timeout. "I flexed so much, my muscles kind of hurt after this and also I stuck my tongue out so much that it was pretty crazy."

Sloan led the ninth-seeded Aggies (25-11) with 12 points and Josh Carter added 10. A&M was trying to get back to the final 16 for the second straight year. Instead, the Aggies fell to 7-10 in NCAA tourney games and 0-4 against UCLA.

"I thought we were in total control, always one step ahead," first-year A&M coach Mark Turgeon said. "I thought we were going to win."

Collison led UCLA with 21 points, including 14 in the first half when he didn't miss a shot from the field or free-throw line.

Love, the newcomer to NCAA tourney pressure, and Collison, the wily veteran of consecutive Final Four appearances, dominated the final 3 minutes. Love converted consecutive turnaround jumpers — one tied it at 45 and the other gave the Bruins their first lead since late in the first half.

"Kevin's two little fallaways were incredible shots," Howland said. "Those are like little H-O-R-S-E shot plays, unbelievable with that kind of stuff on the line. Your season's on the line and he could step up and make those plays. That's why he's a great player."

But Joseph Jones, who bumped and clawed with Love in the post most of the game, got in front of the Pac-10 Player of the Year and scored A&M's first field goal in nearly 10 minutes to tie it at 47.

The first of Collison's two one-handed layins put the Bruins back in front by two with 55 seconds left. Sloan tied it for the final time at 49 before Collison floated in another one-hander, furiously pounding his chest as the crowd exploded.

"That was vintage Darren Collison," Howland said. "Driving down the lane, going right, high off the glass, kissing it in. The second one was really a blessing because that thing kind of rolled in. Believe me, I'm very thankful."

XAVIER 85, PURDUE 78

WASHINGTON — Xavier played its usual brand of in-your-face defense against Purdue, which seemingly couldn't get to the bench during a timeout without being hounded by a player in a white jersey.

The Musketeers were also surprisingly efficient on the other end of the court, and that ultimately made the difference in yesterday's victory that put the X-Men in the West Regional semifinals.

C.J. Anderson and Drew Lavender each scored 18 points and Josh Duncan had 16 for third-seeded Xavier (29-6). The Musketeers shot 54 percent in breaking the single-season school record for wins and setting up a meeting with seventh-seeded West Virginia, a surprise winner over Duke, on Thursday in Phoenix.

"We have a number of different players that can answer the bell on offense," Xavier coach Sean Miller said. "It's a really a unique team to guard, because on different nights different people can beat you."

Keaton Grant scored 19 for the Boilermakers (25-9), who have won 10 straight first-round games but have exited without another win in half those tournaments — including two in a row.

The Musketeers were 26 for 33 at the line and 27 for 50 from the floor against a team that led the Big Ten in field goal percentage defense. The 85 points scored by Xavier were the most allowed by Purdue this season.

"At times," Boilermakers coach Matt Painter said, "we just could not stop them."

Xavier was efficient on defense, too. Although the Boilermakers scored 25 points in the final 8 1/2 minutes, they shot only 39 percent and were 8 for 21 from 3-point range. This, after the Boilermakers scored a season-high 90 points in their first-round game against Baylor.

"Their defense is legit. Definitely legit," said Keaton. "They're not one of those helter-skelter (teams), where it's false defense and it's going to break down in the last five minutes."
